Tea Party wins big in Nebraska

Tea Party favorite Ben Sasse won the Republican nomination for an open Senate seat in Nebraska Tuesday night, after a heated and costly primary battle that drew heavy national attention.

Sasse, a university president, was able to hold off former state treasurer Shane Osborn and dark horse candidate Sid Dinsdale, who had begun to surge in recent weeks. Sasse grabbed 49 percent of the vote with Dinsdale finishing second and Osborn finishing third, according to preliminary returns.

"We were never doing this because we need another job," Sasse told supporters Tuesday night. "We were only going to do this if we were going to talk about big, bold conservative ideas."

The win makes Sasse a huge favorite in November's general election, where he'll face Democrat Dave Domina, an Omaha attorney. The winner will replace Republican Mike Johanns, who didn't seek a second term.
